Brief Introduction of FDA's Guideline on Nonclinical Evaluation of Medical Devices Containing Nitinol In October 2020, FDA of the United States issued the Guidelines for Non-clinical Evaluation of Medical Devices Containing Nitinol, which elaborated the key points of technical review of medical devices containing Nitinol. The contents of the Guidelines are briefly introduced as follows. I. Basic Concepts Nitinol is a near-equiatomic alloy of nickel and titanium, which has the properties of superelasticity and shape memory, and is widely used in cardiovascular devices such as heart stents, valves, guidewires, and other fields of medical devices. Compared with traditional metals such as stainless steel, titanium or cobalt-chromium alloys, nickel-titanium alloys have complex properties and are susceptible to many factors such as alloy composition, thermal processing, surface treatment, corrosion of biological tissues and so on. When evaluating its safety and effectiveness, it is necessary to focus on thermodynamic properties, process sensitivity and so on. II. Key Points of Technical Evaluation (I) Basic information (IV) Biocompatibility It is recommended to refer to ISO 10993 -1 for biocompatibility evaluation. If a nickel ion release test is performed, refer to ISO 10993 -17. (V) Label information It is recommended that the label clearly indicate that the device contains nitinol, suggesting that it may cause allergic reactions in patients,titanium bar gr5, especially in long-term or permanent implanted devices.
